> The eight-billion-parameter end of the Stable Diffusion 3 range, built on an architecture that gave text and image their own separate sets of weights — which is why this was the generation that could finally spell. It arrived on Amazon Bedrock on 4 September 2024 and was switched off on 4 September 2025: twelve months to the day, the exact minimum AWS promises a model before it may end one.
